Issue description

How to set the origin when the cc hosted fields are inside an iframe of a flutter web application?

braintree_v3_widget.dart.pdf

[seankang92129]

In the deprecated v2 SDK documentation there is an enableCORS option when creating the braintree.setup, is there a way to pass this kind of similar options to the v3 SDK when I instantiate the client?

braintree.client.create({

authorization: 'sandbox_MYSANDBOXTOKENIZATIONKEY'

}, function (clientErr, clientInstance) {
}

i also tried to run a sample v3 javascript running on a separate ec2, and I enabled CORS on the express node js server. the page loads, but when I try to generate the nonce, it get the same error.

[seankang92129]

directly interacting with my nodejs server via a separate stand alone browser, it works

i think I found the culprit -- if I replace the webview_flutter plugin for flutter with a different webview https://pub.dev/packages/webview_all, and point the webview to a separate CORS enabled web site, then the issue above about the null target origin goes away.
